Is there an example of how to use the SendCustomCommand method? In particular, I'm trying to access GMail's X-GM-MSGID IMAP extension. (https://developers.google.com/gmail/imap_extensions)
I'm using the following code.
//Returns the IMAP uid
string uid = client.AppendMessage(DRAFTSFOLDER, message);
client.SelectFolder(DRAFTSFOLDER);
ImapResponse response = client.SendCustomCommand(string.Concat("FETCH ", uid, " (X-GM-MSGID)"));
The Response.Message property contains "Success", but the ResponseLines property is an empty list.
I appreciate your help.
